iFR and FFR are equally safe to diagnose and treat heart disease according to largest-ever analysis of new real-world, long-term data
iFR is an innovative pressure-derived index only offered by Philips that is used to assess coronary blockages during interventional procedures.

- The analysis, “Long-term Safety of Revascularization Deferral Based on Instantaneous Wave-Free Ratio or Fractional Reserve,” compares patient outcomes using iFR and FFR in the diagnosis and treatment of heart disease.
- The cumulative MACE risks for each group differentiated by 1.6% (iFR: 21.5%, FFR: 19.9%, HR 1.09 (95% CI: 0.90-1.33 at 5 years).
- iFR is considered the Gold Standard for hyperemia-free physiologic assessment for measuring pressure in diagnostic and interventional procedures [1,4].
